*Coco Bandicoot is the deuteragonist of the Crash Bandicoot series. She is the younger sister of Crash Bandicoot and just like her brother, as well as his girlfriend, she was captured and mutated by Neo Cortex and N. Brio. Coco is highly intelligent and tech-savvy, assisting her brother in his adventures with her laptop and technological expertise.

Coco has green eyes, long blonde hair (usually tied up in a ponytail) with a fringe and she has a blue/pink flower stuck on the side of her head in most of her appearances, she wears a white shirt, blue overalls and pink shoes. Just like Tawna, Coco is a anthropomorphic female bandicoot and has a more human shaped anatomy (in contrast to Crash's cartoony appearance), but unlike her, Coco is younger and shorter in comparison.

In Crash Bandicoot 4: It's About Time and Crash Team Rumble, Coco's physical appearance became more cartoony and dresses similarly to her original design with the white T-shirt, overalls, ponytail, and pink shoes. However, she now wears several additional accessories that makes her look more like a mechanic, including a pair of goggles on her forehead, a pink utility belt with a item pouch attached to it, and a heart-shaped patch sewed to the right knee of her overalls. She no longer has a flower in her hair but now wears an earring on one ear, a pink bracelet over her right wrist, and has a pink training bra and boyshorts with white trim which serve as her underwear, Coco now carries a sticker-decorated tablet in place of her usual laptop computer. In addition, her head is more flat and oval shaped, she has no light yellow fur going down her stomach as shown by her Rawkit Hed skin, and instead she now has light yellow fur at the ends of her three-toed paws as shown by her 360 Noscope Skin.

Crash Bandicoot 4: It's About Time expands upon the new elements that were added to Coco's personality while also retaining the smarter and mature aspects of her personality. In addition to being a lot more cheerful and silly, she is more adventurous, outgoing, mischievous, dynamic, and easygoing. Coco also has a more excited, upbeat, and can-do attitude when it comes to joining Crash on his adventures or fighting enemies. She does occasionally get annoyed and grossed out by Crash such as when he jumped into her arms after being frightened by N. Brio and when he picked up the egg that N. Brio laid, but for the most part Crash and her often come to an agreement on things. In the ending, Coco cheerfully plays video games with Tawna and then encourages Crash to join them. Coco's interest in video games is further emphasized when it is revealed that she became an esports champion in the epilogue.

While earlier games tended to convey them more as an equal brains and brawn division, recent games imply Coco to be a more stable successor to Crash as a result of being the later of Cortex's bandicoot mutants. In It's About Time, she tends to outclass Crash as much in the physical side of things as the intellectual side, always being nimble and cautious enough to avoid the same pratfalls as her brother. Her brattiness is also heavily dialled down, with her charisma and intelligence tending to make her the de facto leader and more popular face of the group, who are relatively more disinterested or impatient with Crash's dopiness. Her On The Run bio states Coco could easily supplant Crash as the world's savior if she wanted to.

Coco also has a habit of taking her laptop, or tablet, anywhere she goes. In Crash Bandicoot N. Sane Trilogy and Crash Bandicoot 4: It's About Time, Coco always carries it while the player is controlling her. She doesn't appear to be too concerned with it getting damaged however, as she is willing to use it to shield herself from boxes falling on her head and to grind on rails. She treats her phone in a similar manner, as she will throw it in the air as it starts to malfunction in one of her idle animations and she even throws it on the ground and kicks it in one of her podium animations in Crash Team Racing Nitro-Fueled.*
